From certain viewpoints it is undoubtedly true that opportunities in the RAF, indeed the forces as a whole, are not what they were even 15 years ago (fewer overseas postings, more beancounting etc.)
However; I think it still has a lot to reccomend it; otherwise I wouldn't be in (I have a highly "transferrable skill" with nigh on guaranteed emloyment in civvi street).
The people you meet are still on the whole some of the best guys (and gals, sorry!) you'll come across, pay is very competitive and when combined with the low cost of living, disposable income is favourable. Finally it's better than working in an office in the city, with a load of choppers watching the clock till the end of the day and looking forward to your hour and a half commute home.
Look into it, try and get some experience of what you will be doing and meet chaps doing what you will be doing in the near future and work out if it is for you.
Best of luck and for God's sake don't join the RN!!
